                                        <p>Thomas( in charge of the Ace Test Assembly project) recruited <strong>Ted Newman</strong> and <strong>David Clayden</strong> who were electronics expertise. The small <strong>Electronics Section</strong> in the <strong>Radio Division</strong> which they joined was established as a separate unit in NPL, known as <strong>TRON</strong> on April 1948 and led by <strong>FM Colebrook</strong> who took an immediate and positive interest in ACE.</p>
                                
                                        <p><strong>G G Alway</strong> and <strong>Donald Davies</strong> joined the ACE group in Mathematics Division on 18<sup>th</sup> August and 1<sup>st</sup> September 1947 respectively. At the same time the work on the Test Assembly was ceased.Turing also left getting frustrated by the lack of progress in the project.</p>
                                
                                        <p>This eventually led to the development of the <strong>Pilot ACE</strong> Computer by the joint effort of the Mathematics and Electronics Section of NPL, which successfully ran it's first simple program on May 1950.
